IWAPS 2023

3rd International Workshop on Advances on Privacy Preserving Technologies and Solutions

to be held in conjunction with the 18th International Conference on Availability, Reliability and Security
(ARES 2023 – http://www.ares-conference.eu )

August 29 – September 01, 2023

The availability of massive amounts of data, coupled with high-performance cloud computing platforms, has driven significant progress in artificial intelligence and, in particular, machine learning and optimization. It has transformed into a fertile surface for cyber-attacks skyrocketing the cyber risk of involved industries and impacting several areas, including computer vision, natural language processing, transportation, trust computing, identity management and psychological manipulation.

This workshop aims to strengthen security and privacy through research and relevant activities in the models and design of secure, privacy-preserving and trust architectures, investments in cyber-defense, data analyses, fusion platforms, protocols, algorithms, services, and applications for next generation systems and solutions. We especially encourage security and privacy solutions that employ innovative machine learning techniques to tackle the issues of inspecting large data volumes, cyberattacks, and variety problems that are systemic in IoT platforms, theoretical and practical challenges related to the design of privacy-preserving AI systems and algorithms and will have strong multidisciplinary components, including soliciting contributions about policy, legal issues, and societal impact of privacy and affect the cyber risk of the participating entities.

The 2023 IWAPS will bring together researchers, engineers, and practitioners to present and discuss latest advances and innovations in theories, infrastructure, schemes, and applications for secure computation, privacy technologies, security economics, human computer interaction, as well as to identify emerging research topics and define the future trends.

The workshop is co-organized from the following European Commission (Horizon 2020 Programme) projects:

The 3GPP Common API framework (CAPIF) – open-source implementation and innovation potential
During the last decades, the use of Application Programming Interfaces (APIs) has served as a bridge between mobile operators and start-ups in emerging markets. Operators have begun to consider whether to open their APIs, starting from APIs related to mobile messaging, operator billing etc. In addition, the recently witnessed convergence of IT and Telecom worlds has contributed a lot to putting APIs in the epicenter of network programming and service provisioning. A representative example that proves this statement is the 5G Service Based Architecture (SBA), which has been designed based on the flexibility that HTTP/2 Restful APIs to provide interaction among 3GPP network functions. In this context, and in order to avoid duplication and inconsistency among the various API specifications that 3GPP has released, the specification of a common API framework (CAPIF) has been considered. In the framework of EVOLVED-5G project (https://evolved-5g.eu/), Fogus Innovation & Services P.C. and Telefonica Spain have developed and provide as an open-source product the Core Function of the CAPIF (namely the CCF), together with ready to use templates for compliant API service provide/consume entities. In the invited presentation, we will delve into the concept of network core openness through the exposure of CAPIF compliant APIs, and we will discuss the innovation potential that emerges by enabling a secure and interoperable interaction of third-party applications with network functions.

Dr. Dimitris Tsolkas holds a Ph.D. degree from the Department of Informatics and Telecommunications, National and Kapodistrian University of Athens (NKUA). He is currently a Senior Research Fellow at NKUA and he also leads research and development activities in Fogus Innovations & Services P.C, SME, Greece.
